No, converting JNG to PSB does not cause additional quality loss — PSB uses lossless compression. However, any artifacts already present in the original JNG file will persist in the PSB output.
PSB files are typically 2-5x larger than equivalent JNG files because PSB preserves all pixel data. This is expected and necessary for lossless quality.
Yes, PSB supports transparency. Alpha channel information from JNG is preserved during conversion.
